centrifugal pump

Recently GN solids control shipped one batch of decanter centrifuge with sludge transfer pump for environmental engineering company abroad, this is for non-oil & gas industry application. The equipments list including:


2 units of 9 inch bowl mini decanter centrifuges, we have 3 models for the 9 inch bowl decanter centrifuge, GNLW223D & GNLW223D-VFD, GNLW224D & GNLW224D-VFD, GNLW224EP series, the 9 inch mini centrifuge can be used for core drilling waste water treatment to recovery more water and for environmental protection. The GNLW224EP series decanter centrifuge can be widely used for different waste water treatment, we can provide customized design to archive better treatment result. The difference of these models are bowl length, back drive motor and differential speed. The longer time of the waste water stay in the clarifier section, the better of the discharged water treatment result.


Centrifugal pump, which can be used as sludge transfer pump, charging pump, feeding pump and trip pump, all the parts are interchangeable with world famous brand centrifugal pump, the pump casing and impeller are made of hard ductile iron alloy for better abrasion resistance.


Sludge vacuum pump can be used as transfer pump of different materials, like drilling fluids, drilling cuttings, animal waste, industrial waste, oil contaminated soils, sand, oil sludge, hazardous waste and others. It is 100% air operated pump without electricity power consumption, but it requires air compressor for air supply and provide pressure. We have 3 models of vacuum pump with 10m3/h 20m3/h and 40m3/h nominal flow rate for option, the actual flow rate will depends on the material density, viscosity and the suction/discharge distance & depth. The small model is movable design with wheels and the bigger model frame is fixed.
If you need a solution for waste water treatment solution, pls contact with GN solids control freely.

Recently one set of liquid mud plant are ready for shipment to South America. It is one of the three components of the complete liquid mud plant for this client, the client take this part as first phase project, it consists of mud mixing tank and storage tanks.


The mud mixing system is a square tank with 400bbl capacity, two each of special designed dust free mixing hopper are vertical installed on the mud tank and drived by 2 units of slurry pump for mud mixing. 2 units of mud agitator are agitating the mud to prevent it from precipitation in the tank bottom, the mud gun are installed as mixing and transfer of mud which is drived by centrifugal pump. The tank accessories including hand rails, pipeline, valves, walkway, stairs, and one unit of operation table, there is a stair to walk on and easily take the dry bulk chemicals and put it on the mixing hopper.


The mud storage system including 14 units of cylinder tanks in 2 rows and connected by pipelines and controlled by valves, the gun line outside the cylinder tank to transfer the mud flexible. The mechanical liquid level meter outside the vertical tanks can easily check the mud level by the operator.
2 units of centrifugal pumps are installed on both end of the storage system and connected by pipelines as transfer pump, they can transfer the mud from any storage tank to mixing tank, and transfer mud from mixing tank after mixing to any storage tank. All the gate valves, bufferfly valves, and all the rubber parts in the system are all oil resistant material for longer working life. The system color is customized blue color, we can also paint with client’s LOGO if required.
If you need liquid mud plant for onshore or offshore, pls contact with GN solids control.

Recently one set of CBM drilling rig mud solids control system are ready for shipment for coal development company. The technical configuration is as below:

5) 1 unit of Jet mud mixer, including venturi hopper and mixing pump
6) 3 units of Centrifugal pumps, which is 100% interchangeable with world famous brand pump, the pump casing and impeller are made of hard ductile iron for better abrasion resistance.
7) 1 unit of decanter centrifuge to separate fine solids from 5 microns to 7 microns, to reduce the solids content. The submersible slurry pump will transfer the clean fluids to decanter centrifuge from desilter compartment, the clean fluids are collected in the mud tank.
8) Several units of mud agitator

Recently one unit of mud cleaning system for offshore platform is ready for shipment. Different with normal design drilling mud cleaning system for onshore drilling, the mud cleaning system for offshore is with different features, like compact design, convenient transportation, offshore lifting frame, explosion proof standard to meet offshore drilling requirement, painting and coating to meet offshore requirement for better corrosion resistance.


The technical configuration is as below:
1) One unit of linear motion shale shaker, the discharged solids are collected by buffer box and collected by screw conveyor, which can transfer the drilling waste to cuttings box. The shale shaker are installed on the mud tank with offshore standard lifting pad, it needs to be lifted to the offshore platform frequently, the safety should be assured. All the mud tank pipelines are layout outside for convenient maintenance and operation. All the valves, fittings, flanges are all oil resistance material for longer working life. The shale shaker equipped with 2 ea Italy Oil brand vibration motor, the shaker screens are produced comply with API RP13C standard, with 3 layers stainless steel material wire mesh, composite material frame for longer working life. The shaker screens fixing method is by wedges.


2) One unit of mud cleaner (desander, desilter and shale shaker 3 in 1), the desander cone and desilter cone are all made of 100% polyurethane material for longer working life. The bottom shale shaker is same model with the shale shaker, the shaker screens are with same dimension. The shaker deck bottom are made of stainless steel material for better corrosion resistance.
